Experienced gardeners share their insights in answering this question :
Sounds like a problem with the governor. Start it up. Don’t engage the blades. Drive to a hill. Idle all the way down. Try driving up the hill. The motor should pick up when it slows while pulling up the hill. If it doesn’t, the governor isn’t working right.

If your John Deere won`t crank and all you hear are clicking sounds when you turn the key, you likely have a bad battery or a bad connection somewhere between the battery and the starter. Double check that the alternator and battery connections are clean and tight.
Its your starter, more precisely, the starter mechanism (clutch/bearing) is not engaging the engine. It can be misaligned, broken teeth, foreign debris stuck in the mechanism, or just dirty and needs cleaning/grease.
Your Mower Won`t Start:
Other possible causes include: Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas.
Check/clean/tighten all connections on battery/solenoid/starter/Ignition switch and neg(-) cable to frame or motor. Check to ensure all safety features are working properly and not engaged. Check for an inline fuse, bypass solenoid to see if engine cranks if it does replace solenoid, if no crank replace starter.
Common problems on the list include things like uneven grass cutting, slipping belts, or minor engine problems. John Deere also claims that lighting issues and battery problems are common. Still, John Deere tractors are largely reputed for their reliability.
Buzzing sound: This usually indicates poor current flow as the buzzing sound means the current is making its way to the solenoid but could not activate the plunger to engage the pinion gear and flywheel of the starter motor.
A Dirty Carburetor Can Cause a Lawnmower To Start Then Die
By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.
Clear the mower deck of debris
Grass clippings can clog the mower deck, especially while mowing a wet lawn, preventing the blade from turning. If the starter rope seems stuck or is difficult to pull, then it`s probably due to a clogged deck.
A clogged fuel filter is most commonly caused by leaving old fuel in the lawn mower. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the fuel filter and make the engine hard to start.
A full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.
The most common cause for the engine not turning over is simply the battery. Either the battery itself is dead, the terminals are corroded so the current can`t travel through them, or the battery cables themselves are damaged. Inspect your battery terminals and cables, and test the battery.
If the engine cranks but will not start, this may be caused by damaged wiring to the high pressure fuel pump. Wiring to the pump can be chafed, which causes the pump to stop working. The chafed wires will need to be accessed and repaired.

Lawn mower cranck but wont start…
Since you already checked for spark and air I would drain all the fuel out of it and check that fuel for water. Over time some lawn mowers end up with contaminated fuel. You can see the water sitting on the bottom of the fuel if you let it stand for a bit in a small plastic bowl.
Be sure to empty and dry out you fuel can as well. Especially if the mower stopped running right after a refuel. Which is a good sign your gas can is contaminated too.
I have had a poulan pro 550 series push mower for almost 1 year at the end of the season last year the mower would start briefly and then stop. i have cleaned out the air filter and that did not help.the mower started, i made one revolution around the yard 3/4th of the way the mower quit. I then primed the mower it started then quit and now it will not start at all. Does anyone have any suggestions of what to do. Thanks
There is a little spring that works the carburetor arm. If that popped off then the mower will not run.
I have trouble starting a toro walk behind mower
All, I thought my carb was shot, so I replaced it. Still, start but no run (and had to use starting fluid). THEN!!! I noticed the spring to the “rev limiter” (just below and towards rear of carb) was not “tight”. The stupid bracket that holds the end of that spring had been bent down ~1/16″ and that caused all this heartache. CHECK YOUR REV LIMITER!!!
I have a Poulan push mower that after mowing in a ditch started making a loud noise and running rough. It almost sounded as if metal was hitting metal. The mower was vibrating more than normal. I checked under the mower and nothing is hitting. After a few times of stopping the mower engine because it sound as if it is going to die down the mower will not start now. The shaft does not appear bent and the blade appears ok. The mower has oil, a good spark plug and a clean air filter. It was running fine until that moment. I did not see anything that I hit but it is possible I hit something in the ditch like a pine cone or branch. What could the problem be and how would I go about fixing it?
If you are sure the oil level is correct then it sounds like it’s about to die, unfortunately. A pine cone shouldn’t cause any damage, but a large branch may do so. Was it smoking before you shut it down? The vibration could be caused from a bent blade. It could also be caused from a part breaking in the motor. I wish I could have given you better news!
I have a problem with a Black and Decker electric lawn mower model MM525. While cutting some high grass today, the mower slowed down, then quit and would not restart. I checked the electrical outlet and there was no power–the fuse was burned out in the switch box. I replaced it, tried again, and again it would not start or even give any response at all, but again it blew out the fuse in the box. The fuse is 25A and the mower is only 12A so that’s not an issue, besides, I’ve used this mower from that outlet for about 4 years since I first got the mower and never had any problem before. My question is: is whatever is causing the mower not to start and to blow out my fuse something that can be repaired or should be? Thanks.
I can think of only one or two things that are causing your problems. It could either be approx. a $14.00 switch in the handle that has shorted out, or 2 bad brushes $1.75/ea.on the armature (motor). Both are fairly simple fixes with just a screwdriver and maybe pliers. You might also check and see if the power cord has been chafed or damaged and is shorting out.

Where is oil drain plug on MTD mower – Mtd LAWN MOWER PART # 683-04163B FRAME Assembly:RIDER
If it isn’t on the bottom of the engine (above the blade) then you don’t have one. This is not that uncommon. When you need to drain the oil, FIRST- pull the spark plug wire off!!! Then remove the dip stick or filler plug and turn the unit upside down and drain the oil.
Lawn mower motor runs good, the drive wheels run good but the blade won’t stay enguaged. Thanks
Check your cable that controls the blade engagement.
Lawn Mower Won’t Run
Ya didn’t give much info but it sounds like the carb had plenty of time to varnish up. take the carb off and clean it make sure you take the fuel bowl off and clean the floate and floate needle good. an auto parts store will have what you need to do everything with
